Leonard McComb studied at Manchester School of Art and subsequently at the Slade School of Fine Art from 1956 to 1959, followed by a Postgraduate in sculpture, also at the Slade, in 1960. He went on to teach at various art schools, including Oxford Brookes University, Sir John Cass College, Slade School of Fine Art, Royal College of Art and Goldsmiths College, and in 1974 he founded the Sunningwell School of Art, Oxford.

Having destroyed most of his early work, McComb was included in the exhibition 'The Human Clay' held at the Hayward Gallery in 1976, his first solo show being held the following year at the Coracle Press. In 1983 an Arts Council touring exhibition entitled 'Leonard McComb Drawing Painting Sculptors' was organised by the Museum of Modern Art, Oxford and shown at the Serpentine Gallery, London; City Art Gallery, Manchester; Gardner Arts Centre, University of Sussex and the Fruit Market Gallery, Edinburgh. His work continued to be exhibited in many important group shows including the Whitechapel Art Gallery in 1982, the Tate Gallery in 1984, the Hirshhorn Museum, Washington D.C. in 1986 and the Museum of Modern Art, Brussels in 1987.

Among McComb’s many awards are the Royal Academy’s Jubilee Award (1977); Korn Ferry Award (1990); Times Watercolour Prize (1992 and 1993); Nordstern Print Prize (1997); and the RWS Prize (1998). McComb has received many major commissions for private and corporate collections throughout the UK, Europe and the USA. In 1999 he completed a commissioned portrait of the novelist Doris Lessing for the National Portrait Gallery, London. The following year he was selected by the Vatican to design a Jubilee Medal, featuring Pope John Paul II and the late Archbishop Basil Hume, for the worldwide series to commemorate the Millennium.

McComb was elected Royal Academician in 1991 (ARA 1987) and in 1995 was elected Keeper of the Royal Academy, placing him in charge of the Royal Academy Schools until 1998. He was made an Honorary Member of the Royal Watercolour Society and the Royal Society of Printmakers in 1996. McComb lives and works in London.
